Coccidiosis is an intestinal disorder of poultry and often caused by simultaneous infections of several Eimeria species. GAPDH is one of the immunogenic common antigens among Eimeria tenella, E. acervulina, and E. maxima identified in our previous study. The present study was performed to further evaluate its immunogenicity and protective efficacy. The genes of GAPDH cloned from E. acervulina a...

DE VOS, A.]. & DOBSON, LYNNE D. Eimeria chinchillae DeVos & Vander Westhuizen, 1968 and other Eimeria spp. from three South African rodent species. Onderstepoort ]. vet. Res., 37 (4), 185-190 (1970). Eimeria chinchillae DeVos & Vander Westhuizen, 1968, an organism originally described from the chinchilla and subsequently shown to be transmissible to other rodents, was found to occur naturally i...

Prevalence of Eimeria species parasitizing rabbits (Oryctolagus cuniculus) in Taiwan were investigated. Six Eimeria species, namely: Eimeria media (prevalence, 158/642; 24.6%), Eimeria magna (101/642; 15.7%), Eimeria perforans (58/642; 9.0%), Eimeria coecicola (46/642; 7.2%), Eimeria piriformis (16/642; 2.5%), and Eimeria exigua (9/642; 1.4%) were observed. The overall prevalence of these cocci...

AIM To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. MATERIALS AND METHODS A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation techniques. Sporulation of the oocyst w...

Infectious and metabolic disorders are common in poultry and cause stress, poor performance, and mortality that results in considerable economic loss. Identifying the nature of stress in chickens will assist the development of appropriate measures to improve health and welfare. Acute phase proteins are hepatic proteins, the blood concentrations of which change significantly in the event of many...

Partial plastid 23S and nuclear 18S rDNA genes were amplified and sequenced from 2 morphologically similar Eimeria species. E. antrozoi from a bat (Antrozous pallidus) and E. arizonensis from deer mice (Peromyscus spp.), as well as some other Eimeria species from bats and rodents. The phylogenetic trees clearly separated E. antrozoi from E. arizonensis. The phylogenies based on plastid 23S rDNA...

Eimeria species are frequently found in water buffalo (Bubalus bubalis) in Brazil. Here, we report those Eimeria spp. that infect buffalos during their first year of life. Fresh fecal samples were examined from 2 groups (1 group/yr for 2 yr, 2000-2002), each with 18 water buffalo calves (both sexes), from birth through 12 mo of age, in Selvíria, MS, Brazil. Five oocyst morphotypes were observed...

18 The nucleotide sequence data reported in this paper appear in the DDBJ, EMBL and 19 Genbank® nucleotide sequence database with accession number CS000361. Abstract 1 Eimeria tenella is the causative agent of coccidiosis in poultry. Infection of chicken 2 intestine begins with ingestion of sporulated oocysts releasing sporocysts which in turn 3 release invasive sporozoites. The monoclonal anti...

The enteric disease coccidiosis, caused by the unicellular parasite Eimeria, is a major and reoccurring problem for the poultry industry. While the molecular machinery driving host cell invasion and oocyst wall formation has been well documented in Eimeria, relatively little is known about the host cell modifications which lead to acquisition of nutrients and parasite growth. In order to unders...

BACKGROUND In this study, the presence of resistance to diclazuril, amprolium+ethopabate and salinomycin, representing some of the commonest anticoccidials in Iran's poultry industry, against three mixed Eimeria field isolates were investigated. METHODS Three Eimeria field isolates, collected from typical broiler farms in Iran, were propagated once, inoculated to 480 broilers, comprising 30 c...
